7 Application filed. September 4, 1930. Serial No. 479,665.

My invention aims to provide improvements in D-handles for shovels and the like, and the method of assembling the casing.

. Reference is hereby made to my divisional application Serial No. 521,180, filed March 9, 1931.

In the drawing, which illustrates a preferredfembodiment of my invention:

Figure'l is an elevation view of my invention showing the upper end ofa split stale incased in a sheet metal casing;

Fig. 2 is a View of the sheet metal casing before attachment to a stale, the lower portion being in cross-section to show the means which holds the parts of the casing in assembled relation;

Fig. 3 is a part section and part elevation of a portion of the casing showing the method of assembly of the two parts;

Fig. 4 is a View of the parts shown in Fig. 3 after they have been completelyassembled; and i Fig. 5 is a section taken onthe line 55 of-Fig. 4. i

With reference to the drawing, I have shown a D-handle which includes a casing 1- preferably formed from" sheet metal; and combined with the split end of a 'stale2 and a grip piece 3, as shown in Fig. 1. The general construction of the handle, except for the means by which the casingparts are secured together, and the method of assembly of the three parts of the handle is substantially the same as shown and more fully described in my co-pending application Serial No. 341,131, filed February 19, 1929. Since my present invention relates to improvements in the casing and. the method of assembling the parts thereof, it will not be necessary to describe in detail the general construction of the handle and the method of assembly. 7

My improved casing l is formed from two identical hollow sheet metal parts, each of which is semi-cylindrical in crosssection and has aflat face provided by inwardly bent flanges 4, 4 as shown-in Figs. 4 and 5. Each :part also has a vertical flange 5 adjacent.

to the stale-receiving end and a hook shaped .ingand splitting of the'stale beyond-that A portion 6 extendingfrom one end ofaflange 4, as best shown in Fig.2. 1 r

When the parts of the casingl aresecured together, as shown in Fig.1.2, the flange 5 of one part underlies a portion of another part 55 (Fig. 5) and is weldedjthereto to securepthe parts together. Also, the hook portions 6 hook under the terminal edges of flange portions 4 (Fig. 2), so that whenthe side armsof the casing are bent into Y-sh-aped formation the casing will not spread beyond the :hook portions and therefore the stale will not be split. I 7

While the handle construction shown and described in my co-pending application referred to above issatisfactory for general purposes, it has been found. that the casing parts will pull apart where they are joined together when placed under heavy strain such as when the handle is used for a pry. Therefore I have overcome this objection by the'construction used inmy present form ;of device because,,when the wooden arms of the stale are forced into the hollow arms of the casing 1, the hook portions are held. 7

tightly against the flanges 4 and provide,

with the welded portions, a strong durable connection to prevent separation of the cas point.

Themethod'of assembling the 'parts of the casing is, I believe, unique because the construction is such that the parts can be assembled only by placing them together with their flat faces in engagement and withthe longitudinal axis of onepart angled relative to the longitudinal axis of the other, as shown in Figure 3. This is necessary because of the opposed hooks which can be engaged beneath the flanges 4 only in this manner and there, after rotating one partrelative to the other to bring them into thepositions shown-in Figs. 2 and 4'. Bythis method of assembly,

all of the elements may be preformed and 95 i "portionsare oftsetfrom the center (5) ofeac h '100 casing part so as not to interfere with each other and to facilitate assembly as well as to provide a strong assembly across the entire Width of the casing.

When the parts are assembled by the method just described they are securely fixed together at one end and the outer surface is smooth and presents a neat appearance. While I have illustrated and described a preferred embodiment of my invention, I do not wish to'be limited thereto because the scope of my invention is best defined by the following claims, some of which are intended to be of such scope asto cover other varia tions one of which is shown in my co-pend ing application filed herewith.

7 Claims. f 1. In a D-handle construction for shovels and the like, a sheet metal casing composed of two similar pieces each having a flat inner face facing theflat face of the other and each piece having means adjacent to its flat face interlocked, with theother piece to lockthe two pieces together. 1

2. In a D handle construction for shovels and the like, a sheet metal casing composed of two similar pieces each having a flat inner face facing the flat face of the other and each piece having a hook-like finger extending from the flat face and engaging the material of the flat face of the other piece to lock the two pieces together.
